Three dimensional tracking of gold nanoparticles using digital holographic microscopy
Frédéric Verpillat, Fadwa Joud, Pierre Desbiolles +1
In this paper we present a digital holographic microscope to track gold colloids in three dimensions. We report observations of 100nm gold particles in motion in water. The expecte…
Holographic microscopy for the three-dimensional exploration of light scattering from gold nanomarkers in biological media
Fadwa Joud, Frédéric Verpillat, Pierre Desbiolles +2
The 3D structure of light scattering from dark-field illuminated live 3T3 cells marked with 40 nm gold nanomarkers is explored. For this purpose, we use a high resolution holograph…
Digital Holography at Shot Noise Level
Frédéric Verpillat, Fadwa Joud, Michael Atlan +1
By a proper arrangement of a digital holography setup, that combines off-axis geometry with phase-shifting recording conditions, it is possible to reach the theoretical shot noise…
Exploring shot noise and Laser Doppler imagery with heterodyne holography
Michel Gross, Frédéric Verpillat, Fadwa Joud +1
Heterodyne Holography is a variant of Digital Holography, where the optical frequencies of signal and reference arms can be freely adjusted by acousto-optic modulators. Heterodyne…
Shot Noise in Digital Holography
Fadwa Joud, Frédéric Verpillat, Michael Atlan +2
We discuss on noise in heterodyne holography in an off-axis configuration. We show that, for a weak signal, the noise is dominated by the shot noise on the reference beam. This noi…
